Comments starting with # ~
In Vim script comments normally start with double quote. That can also be the
start of a string, thus in many places it cannot be used. In Vim9 script a
comment can also start with #. Normally this is a command to list text with
numbers, but you can also use `:number` for that. >
let count = 0 # number of occurences of Ni!
Vim9 functions ~
`:def` has no extra arguments like `:function` does: "range", "abort", "dict"

White space must also be put before the # that starts a comment: >
let var = 234# Error!
let var = 234 # OK
White space is required around most operators.
